Dirt 3 (stylised as DiRT 3) is a racing video game developed and published by Codemasters for Microsoft Windows, PlayStation 3 and Xbox 360. It is the eighth game in the Colin McRae Rally series. In September 2011, there were reports that a network security problem on the website of an AMD promo had resulted in the loss of 3 million Dirt 3 keys to the public for use via the Steam platform that have then been posted in various places around the internet.
